1 i 8/4 + 2 i 6/3 - 3 i 2/5= 3 + 4 - 3 i 2/5= 7- 3 i 2/5= 6 i 5/5 - 3 i 2/5= 3 i 3/5
3 i 2/4 + 2 i 2/3 - 1 i 1/2= 3 i 1/2 + 2 i 2/3 - 1 i 1/2= 3 i 3/6 + 2 i 4/6 - 1 i 3/6=
= 5 i 7/6 - 1 i 3/6= 4 i 4/6= 4 i 2/3
4 i 2/4 - 3 i 2/3 + 2 i 1/2= 4 i 1/2 - 3 i 2/3 + 2 i 1/2= 4 i 3/6 + 2 i 3/6 -3 i 4/6=
= 6 i 6/6 - 3 i 4/6= 3 i 2/6 = 3 i 1/3
